I’ll open by stating that this is one way to manage a long running process (LRP) — not de facto by any stretch. In my experience, the best possible product comes from concentrating on the specific problem you’re dealing with, while delegating supporting tech to other libraries. In this case, I’m referring to the act … Read more
C11 clarifies the answer to this question, in the draft C11 standard section 6.8.5 Iteration statements added the following paragraph: An iteration statement whose controlling expression is not a constant expression,156) that performs no input/output operations, does not access volatile objects, and performs no synchronization or atomic operations in its body, controlling expression, or (in … Read more
It’s not wrong per standard, it’s just a bad design. Constructors don’t usually block. Their purpose is to take a raw chunk of memory, and transform it into a valid C++ object. Destructors do the opposite: they take valid C++ objects and turn them back into raw chunks of memory. If your constructor blocks forever … Read more
If you want to study termination properties in depth, programs using successor-arithmetics are an ideal study object: You know a priori what they should describe, so you can concentrate on the more technical details. You will need to understand several notions. Universal termination The easiest way to explain it, is to consider Goal, false. This … Read more
There is no guarantee that you will iterate over all your dict entries if you mutate it in your loop. From the docs: Iterating views while adding or deleting entries in the dictionary may raise a RuntimeError or fail to iterate over all entries. You could create an “enumerated” infinite loop similar to your initial … Read more
One line of code using Java 8: line = buffer.lines().collect(Collectors.joining());
As per the javadoc for Scanner: When a scanner throws an InputMismatchException, the scanner will not pass the token that caused the exception, so that it may be retrieved or skipped via some other method. That means that if the next token is not an int, it throws the InputMismatchException, but the token stays there. … Read more
There is no difference in bytecode between while(true) and for(;;) but I prefer while(true) since it is less confusing (especially for someone new to Java). You can check it with this code example void test1(){ for (;;){ System.out.println(“hello”); } } void test2(){ while(true){ System.out.println(“world”); } } When you use command javap -c ClassWithThoseMethods you will … Read more
You can also use a while loop: while (true) { //your code }
